Sodium is a lot more abundant than lithium. Scaled up this could be a breakthrough in battery cost per kWh.

lithium cost $22/kg. 1 KW/h is 0.2kg lithium in 5 kg of batteries that costs $100 retail on AliExpress. So it isn't about lithium price. It seems that just manufacturing and delivering a 1kg of low-mid-complexity stuff comes about $20/kg. (just for example - a car weights 1000-2000kg and costs $30K)
